SeaISO Rugged USB Isolator

SeaISO Single Port Ruggedized Inline USB Isolator Cable (UL Recognized)


Out of stock


The SeaISO™ ISO-1R is a single-port, ruggedized inline USB isolator cable that offers a simple method of protecting host and field equipment from damaging transients and surges commonly found in commercial, industrial and medical environments. The ISO-1R is UL Recognized, in accordance with EN60601-1 3rd Edition, and protects both the data and power lines with 4 kV of medical-grade isolation between the host control system and connected USB equipment.

The ISO-1R utilizes Sealevel’s expertise in military-grade designs by incorporating a ruggedized, TPE overmolded cable “bump” that improves the reliability and durability in medical, industrial and mobile applications. The isolator is essentially a 6 foot, ruggedized USB cable extender. The “bump” includes an integrated loop for convenient hanging or mounting. The host connector is a Type A right-angle USB connector. The other end has a high-retention Type A Female USB connector that helps prevent accidental cable disconnections.

The ISO-1R is USB bus powered, eliminating the need for external power. The efficient DC/DC design allows energy transfer over the isolation barrier. The isolator provides up to 300 mA to a downstream USB device when connected to a standard 500 mA USB port. Additionally, the isolator provides a full 500 mA to a downstream device when connected to a USB port capable of sourcing 1 A, or greater.

Supported in Microsoft Windows, Linux, and other USB aware operating systems, the ISO-1 requires no separate drivers and is easy to install. Simply plug the isolator into an available USB port with the included cable, and it is automatically recognized as a generic USB hub device. The ISO-1 is a USB 2.0 compatible device connecting to the host over a high-speed link and features full-speed (12 Mbps) data rates between the downstream USB device.

Standard operating temperature range is -20C to +60C and extended temperature ranges are optional. If you need a USB isolator with removable cables, see the ISO-1. If you need an OEM USB isolator to integrate into your application, see the ISO-1-OEM.

Note: This item is intended for OEM applications and a minimum order quantity (MOQ) may apply. For low volume applications and testing, please use the ISO-1 or ISO-1-OEM versions. Please contact your sales representative with any questions.
